Dormer E544 HSS BA Spiral Flute Tap 4 BA Spiral Flute

Designed for superior performance in challenging threading applications, the Dormer E544 HSS BA Spiral Flute Tap excels at cutting threads in blind holes. Its specialised spiral flute geometry actively draws chips and debris upwards and out of the hole, preventing clogging and reducing the risk of tap breakage. This makes it the ideal choice for maintenance, repair, and production work where access to the back of the hole is limited.

- Manufactured from high-speed steel (HSS) for excellent durability and wear resistance

- BA (British Association) thread form, specifically 4 BA, for precision fasteners

- Ground thread profile ensures accurate, clean threads and consistent fit

- Suitable for use in a wide range of materials, including steel, brass, and aluminium

- Enhanced flute geometry reduces cutting torque and extends tool life

- Ideal for both manual and machine tapping operations

Combining reliability with practical design, this tap delivers clean threads and lasting performance in demanding workshop environments.
